Ion of fluorine
Webuser guide. Fluoride electrodes measure free fl uoride ions in aqueous solutions quickly, simply, accurately and economically. The measurement of fl uoride in drinking water and wastewater using an ion selective electrode is an EPA approved test procedure. EPA-approved ISE test procedures for fl uoride in WebFluorine, F It has seven electrons in its outer shell. It gains an electron from another atom in reactions, forming a fluoride ion, F –. Note that the atom is called fluorine, but the ion is called fluoride. A fluoride ion has the same electronic structure as a neon atom (Ne). Why does fluorine want to gain electrons?
